Sony develops paper-based disc

Sony and Toppan Printing, a large Japanese printing company, have developed a Blu-ray Disc based on a paper substrate which promises to be more environmentally friendly and secure when destroyed than traditional discs, they say.

Blu-ray Disc uses a blue laser to achieve a storage capacity of around 25GB or around five times that of current DVD discs. It is one of a number of new optical disc storage formats that are being targeted at applications such as storage of high-definition video.
